Go get a notebook and a pen. Sit outside. Write about something that's on your mind from a different person's point of view. You'll discover what he's talking about.

This isn't unusual or new-age at all. Writing from a second point of view or imagined conversations as a tool for thinking goes back to at least Plato's Dialogues.

I seem to have very little on my mind, probably why I struggle to maintain journalling.

If you know you know. We all think differently.
